Pneumatic valve manufacturers pneumatic ball valve selection key points, how to choose correctly?
Pneumatic ball valves are widely used in chemical, petrochemical and other industries.
Pneumatic ball valve is driven by the piston cylinder ball valve, equipped with solenoid valve, limit switch box, filter pressure reducing valve and other accessories, can realize automatic control. Pneumatic ball valve is generally used for fast cutting, its sealing performance is good, fast cutting speed, is other valves can not be replaced. Also equipped with electric valve positioner, made of pneumatic adjustment ball valve, adjust the flow or pressure of the medium.
According to the form of the cylinder, pneumatic ball valve can be divided into single action and double action. Double action pneumatic ball valve switch needs air source, single action pneumatic ball valve switch needs air source. In case of air source failure or solenoid valve power failure, the valve will automatically reset due to the spring action. For working conditions that require automatic valve resetting in some cases, single-acting pneumatic ball valves may be selected.
There are many kinds of pneumatic ball valves, including pneumatic flange ball valves, pneumatic threaded ball valves, pneumatic ultra-thin ball valves, pneumatic O-type ball valves, pneumatic V-type ball valves, pneumatic three-way ball valves, pneumatic four-way ball valves, pneumatic sanitary ball valves, pneumatic vacuum ball valves, pneumatic insulation ball valves, pneumatic fluorine lining ball valves, etc. Pneumatic type O ball valve is suitable for the two switch cutting, pneumatic V type ball valve is suitable for the adjustment, commonly used in the automatic control of pulp papermaking industry and other medium, pneumatic three-way ball valves and four ball valve is used to convert the medium, pneumatic ball valve is suitable for the health food and pharmaceutical hygiene requirements, pneumatic rubber fluorine ball valve is suitable for the corrosive medium, Pneumatic insulated ball valve is suitable for easy crystallization or room temperature solidification medium, such as asphalt.
